Diagnosis and taxonomic note.
This is one of three very similar species with male forewing venation modified as in Fig 4a, most of the strongly curved radial sector veins and M1 arising from a narrow areole, and with the costa reflexed back centrally to support a fringe of hairs over the discal part of the cell. The forewing pattern has a strongly zig-zagged postmedial that, in the male, tracks the strong curvature of the veins distal to the cell. The females have the postmedial less extensively zig-zagged and a generally more speckled facies; they are difficult to associate with the males. Males of the three species can be distinguished externally by variation in the venation around the areole. The facies of cuneifera is similar to that of the next species except the forewing fringes are usually tinged brownish, and the antemedial is more broken as in the third species in the group. The male areole is very narrow, the radial sector veins arising connate or stalked from it. The male genitalia have the costal process of the valve absent, but the saccular process is strong, upcurved, tapering to a point. The aedeagus vesica is globular with about ten slender cornuti arranged around it. The females have an irregularly shaped bursa with rather thick walls, fine scobination basally and a meandering zone of coarser spining distally. A similar bursa structure is seen in Lyclene luzon Wileman & South comb. n. (Philippines) but the coarser spining is more regular and linear.

Geographical range. Borneo, Peninsular Malaysia, Sumatra, Java.

Habitat preference. This species is recorded from a range of lowland forest types, including heath forest, and lower montane forest as high as 1000m.
